Okay, I'm going to take one for the team. Walgreens has 32gb micro SD cards for $12.99 (if you have their rewards card). I'm giving it to my daughter to use in my old HTC Desire Eye.
BTW the 64gb SanDisk card I had in there failed in a way I've never seen before. I thought I deleted everything off of it before giving it to her in the phone, but everything was still there. I took the card back and tried to format but no dice. Never could get it to format, and it turns out to be a somewhat common failure. I guess it's better than losing info, but not good for privacy if you share cards.
